Have a 800va transformer with two 60v secondary wires. Have two amplifier boards that use a single + 83v. What is the best way to wire these to utilize both secondary windings? Should i half bridge with two rectifiers running each board off each secondary and cap? Right now i have been running it off one secondary, rectifier to two caps in parallel and both amp off the positive 83v.
Can I make two positive 83v terminals one for each amp board? I know this is , just a hobbyist and want to make sure im utilizing my power supply to its full potential. Secondary is two yellow 60v leads. Thanks in advance for any help!

Take each 60Vac secondary winding, rectify them separately and use individual power line decoupling. Then use one 83Vdc output for one amplifier and the other 83Vdc output for the other amplifier.
Excellent, just finished and bass is slamming now! Pretty new at the power supply configurations and wanted to double confirm before i let the smoke out! Thanks for the quick reply! Donated to the site because I dont want to be a taker. Thanks again!
Running them in parallel and using one power supply should be somewhat cheaper due to fewer parts. Be sure to get the phasing correct if you do this.
The difference in performance between the two configuations is negligible in practice, the deciding factor might be component cost or even convenience of layout, physical size of filter capacitors, etc.
For a PA system dual supplies adds redundancy, which is advantageous (partial failure of a PA system is not necessarily a show-stopper, literally)
